Validated validating c
In such a case, the key k needs to be entered securely in each ATM once it is installed.
Such key setup on ATMs is done by splitting the key into two parts and having two different bank officers enter their portions of the keys separately.
Let’s take a look at how to do that with a text field that is only supposed to have a value of either ‘AAAA’ or ‘BBBB’ (yes, I know that this does not make much sense in a real PDF form).
So, if the user enters ‘01234’ we should see an error message that would instruct the user about what type of data is valid for this field.
Now, the PIN is decrypted at the issuing bank who has its offset stored in its database and can re-generate the PIN using the offset, card number and few secret keys.

Another thing I like to do is to display the validation error message on the form in an otherwise hidden field: The problem with our last solution is that if the user saves a partially filled form, and picks it up at a later time, that error message that popped up is long gone, and the only indication that there is something wrong with the form is the modified field color.
So, having a text field contain that error message might be a good idea.
If you look carefully, the ATM cash dispenser installation itself is a critical step.
To start, we create a text field and bring up the properties dialog for the field.
Then we select the “Validate” tab to see the validation options: The default is that the field will not get validated.
